Natural gas liquefaction vessel

A natural gas liquefaction vessel including an increased deadweight tonnage, as compared to a liquefied natural gas carrier (LNGC) of a comparably-sized ship, is achieved by reducing the LNGC's cargo capacity. This difference creates room on the port and starboard sides of cargo tanks to increase the size of the adjacent wing tanks. The increased size of the wing tanks occupy the space created by the reduced cargo tank size of the vessel and may- support a larger upper trunk deck. The ballast wing tanks and smaller cargo tanks increase the deadweight available. With this approach, the larger upper trunk deck of the vessel is able to support an efficient floating liquefaction plant that improves the LNG value chain because it is capable of producing 2.0 - 3.0 MTPA in the footprint of a standard vessel hull, such as for example a Q-Max hull ...

부유식 해상구조물이 개시된다. 본 발명에 따른 부유식 해상구조물은, 발전부의 가스터빈의 압축기로 유입되는 공기를 재기화부의 냉열을 이용하여 냉각시킨다. 그러면, 공기를 냉각시키기 위한 별도의 장치가 필요 없으므로, 원가가 절감되는 효과가 있을 수 있다. 그리고, 냉각된 해수를 이용하여 발전부의 제1복수기의 증기를 응축시키므로, 상대적으로 적은 양의 해수로 제1복수기의 증기를 응축시킬 수 있다. 그러면, 상대적으로 작은 용량의 펌프를 이용하여 해수를 펌핑할 수 있는 효과가 있을 수 있고, 해수가 통과하는 관로가 손상되는 것을 최소화할 수 있는 효과가 있을 수 있다. A floating offshore structure is disclosed. The floating offshore structure according to the present invention cools the air flowing into the compressor of the gas turbine of the power generation unit by using the cold heat of the regasification unit. Then, since there is no need for a separate device for cooling the air, there may be an effect of reducing the cost. In addition, since the cooled seawater is used to condense the vapor of the first condenser of the power generation unit, the vapor of the first condenser can be condensed with a relatively small amount of seawater. Then, there may be an effect of pumping seawater using a pump having a relatively small capacity, and there may be an effect of minimizing damage to a pipeline through which the seawater passes.
